SOUNDJessica Collins

Sound Desk- Yamaha MG32/14FX• 24 channels.• Can have 6 channels (mono/stereo).• Mono- only need it in one side.• Stereo- need two channels. • You can adjust sound on a desk.• You need to use the pan to either

make the sound equal across both speakers or stereo in the centre.

• You need to use the ‘on’ button to turn the channel on and adjust the volume- but making sure the master volume is also up.

• You switch on the PFL button and use the levels to insure the sound isn’t in the red zone but in the orange.

EQ• The 4 green EQ dials

high, 2 Middle and a low are used to minuplate the sound coming through the desk to a pleasing tone. For example if you were sound checking a show you would use the dials to make the singers voice sound the same as there normal voice. It is left to cut the dial or right to boost.

Pan• The pan dial is used to equal the sound between the 2

speakers or create a stereo sound when the dials are both in the middle.

• The 2 white dials are used to apply effects from the built in effects unit. For example you can add reverb. You would not use reverb if you were already in a space such as a church, as the natural reverb would already be good.

PFL and Gain• The gain dial sets how

much sound can come into the desk. The gain allows more or less sound to the speaker.

• You turn on the PFL button which isolates the channel and use the gain to insure the sound is within the yellow on the peak monitor as seen on the next slide.

• It is important to keep the sound within the yellows and out of the red as it means it has reached its peak volume and will become distorted and can result in damaging the equipment as well as sounding unpleasant.
